Higher harmonics in asynchronous machines.
Abstract
The effect of groove bevel on the distribution of higher harmonic fields caused by the unevenness of the air gap is considered. The necessity of taking into account the redistribution of higher harmonic fields when calculating the bevel coefficient and the choice of a rational groove slope value is substantiated. The corresponding experimental data and analysis results on the computer are given. Tab. 2, ill. 4, bibl. 6
